Personally, I feel the monotony of MSQ roulette can be easily fixed by including future key MSQ dungeons in it as you progress through the game.

Personally I feel it would be beneficial to include:
  • The Aetherochemical Research Facility
  • Baelsar's Wall
  • Ala Mhigo
  • The Ghimlyt Dark
  • Amaurot
  • Paglth'an
  • The Dead Ends
  • The Lunar Subterrane

Then once 8.0 is out, add two key DT dungs to the roulette.
The mandatory cutscenes should be kept for new player progression, but just having more variety as the game expands for a player would deal with most issues.
